I'm thinking about getting a foot pedal. Was reading the forums and see that x-keys does one (http://xkeys.com/xkeys/xkfoot.php) and this other site http://www.kinesis-ergo.com/foot.htm.

- I was wondering if anyone else where using foot pedals
- Are they useful
- How many pedals should i get (1, 2, 3, 4, ... etc)
- What is a good one to get (I know a lot people love x-keys but is there a better foot pedal then x-keys)

Kind of don't want to send more then $200 on it.
